Sneak peak of a future update that'll add custom models for various parts in the engine bay
(Could use some help with texturing)
I'm trying to save up for a wheel setup so I can improve my beam mods

This Mod Adds:
Engines:
2.0L EJ207 B4 STI Engine - This is the cool Japanese STI engine the Americans never got - Famous for it's great reliability and power potential with simple bolt-ons
2.5L EJ257 B4 STI Engine - If it weren't for California's strict emissions laws, this engine wouldn't exist - Suffers from ringland and head gasket failure at ~100,000mi - Makes good power though
2.0L EJ205 B4 WRX Engine - This is the Japan only lower end version of the EJ207 engine - Makes similar power to the EJ207 with a simple bolt-on VF37 STI turbo
2.5L EJ255 B4 WRX Engine - The detuned WRX version of the US EJ257 - Makes a lot of power with bolt-ons - Suffers the same high piston tolerance reliability issues with the EJ257
Boxer Engine Model - Working on making it more realistic (Top mount intercooler, realistic hot/cold side turbo piping, realistic turbo location and more)
